Robinair Vacuum Pumps are engineered specifically to meet your A/C maintenance needs and to give you trouble-free operation. Take advantage of our years of experience and know-how developing pumps to help you do your job faster and better.



  • Two Stage Design - second stage starts pumping at a lower pressure to pull a deeper ultimate vacuum.
  • Offset Rotary Vanes - Our proven design creates the deep vacuum conditions needed for a thorough evacuation.
  • Gas Ballast feature - helps keep the pump oil clean by reducing condensation of moisture.
  • Iso-Valve™ - isolates pump from the system with just a 1/4 turn, making it simple to measure rate of rise.
  • Integral Check Valve - prevents pump oil from being sucked into the system if a power loss occurs.
  • Die-Cast Aluminum housing - lightweight but durable.
  • Molded Base - Durable polycarbonate base improves pump balance and minimizes vibration.
  • Designed for use on A/C-R systems using CFCs, HCFCs, and HFCs in conjunction with mineral oil, ester oil, alkyl benzene oil, and PAG oil as lubricants.
